Starvation Diets not slimming in the long term
First your body goes into 'starvation mode' and slows down your metabolism so that you have less energy and don't need as much food.
When you go back to a regular diet, your body decides that it should put on more fat than you had before in case another famine comes. It is cleverly trying to prevent you from starving to death by storing more fuel!
So after every starvation diet binge, you'll likely get a little bit fatter once it's over. Probably not what you want to achieve!
95% of diets are 'starvation diets' - And how many overweight people do you see?
So instead of trying to starve yourself, eat sensibly and exercise more. It doesn't matter what the exercise is. Just do it!
